CHARGING COKE-OVENS.

Patented Mar. 5, 1912.

Application filed November a, 1911. Serial No. 658,327.

To all whom tin nag concern:

Be it known that IJVAL'rImR I-IInY,Pl1. D., a subject of the German. Emperor, residing in Sandal, near \Vaketield, Yorkshire, England, and whose post-o'tfice address is The- Cli'ti', Sandal, near Wakefield, Yorkshire, 'England, chemist, have invented certain new and useful Improvements in Apparatus for Charging Coke-Gyros, of which the followiug is a specification. p

This invention, which originally formed part of application. Serial No. (329390 dated 27th May, 1911, relates to apparatusfor carrying out a niiethod of charging a horizontal coke oven by introducing a charge of a length greater than that of the oven chamber.

Owing to the stamped or compressed charge of coal, which'is used for charging the horizontal coke oven, being of greater length than the oven chamber the compressed charge is stopped by the other end of the chamber before the charging operation is completed and is broken up so that 5 it is made to fill the empty spaces on each side and is brought into contact with the oven chamber walls. A. space is left beneath the door at the bench end to permit passage of as much of the peel of the charging machine as is necessary. When the whole charge is within the chamber the peel can be withdrawn without jamming the charge into the narrower, rain end of the chamber; EV hen the front end of the stamped charge has come against the oven door at the bench end there is a tendency for the part of the charge which has not yet entered thechamber to break up before it is forced into the chamber. it may therefore be advisable to on: ploy side protectors or attach plates to the hack of the charging machine. Such plates may enter the chamber with the char e. The back of the charging machine to which, the side plates may be attached to nnzst best-rong enough to sustain the pressure i. the coal against it when the peel is wi'l'lulrawn. Afterward the back and the s de plates are themselves withdrawn and the oven doors lowered and luted. In some 5 cases the stamped charge is not so easily broken up as in other cases. it may be adisflblc theret'oro to provide the inner face of the doorat the bench end with wedge shaped or other projectiims to aid the break 5 ing up. Or as the ch rgai is being intro duced it may be broken up by tools inserted through the top of the oven chamber.

The invention will be described with reference to the accon'ipanyiug drawings in wbicl i Figure 1 a longitudinal vertical sectionthrough an o en chamber in a bench of ovens and Fig. a sectional plan thereof.

(4 is the peel carrying the compressed charge a which in the position shown has ins-tbcen brought to rest. against the door 2' at the bench end of the chamber, this door having been incompletely lowered so as to allow of passage of the end of the peel be-,

ueath it.v The charge being longer than the chamber yrotrudes from the latter at the ram end and the protruding portion is protected by side plates 0 fixed to the peel, and by the end plate (Z adapted to slide between the side plates. This end plate is fixed to tubes f which are guided. in a plate 70 carried by a frame work fixed to the peel. The tubes are surrounded by helical springs e the ends of; which abut against the plates (Z and 7c respect vely. The, object of these springs is to maintain the plate cl against the end of the charge while the side plates 0 are being withdrawn together with the peel after the completion of the charging operation. Since the length of plate 0 to be withdrawn varies with th length of the protruding portion of the c large, which may not always be the same, provision is made to adjust the compression of these springs. For this purpose ippes at extending through the tubes f are attachcdat one end to the plate 0?. At the other end the ropes are wound up on pulleys adapted to be turned by worm gears on a shaft'n which is locked from rotation in the opposite direction by a pawl IL. During the introduction of the charge the springs are held in the desireddegree of compression by pawl h.

\Vhen the front end of the charge has come against the door 1', the peel a is moved. forward until the protruding portion at the ram end of the charge has been forced into the chamber, whereupon the peel is Withdrawn During this backward movement springs 41, at'ter the pawl /I.- has been released, expand and maintain plate (1 against the end of the charge until the side plates 0 have been withdrawn from the chamber.

'lhe plate is now moved back, it necessary by exerting tension on ropes 7o. suliiciently rying-the same into practical effect, I claim her and a framework associated 1. In a machine for charging a horizontal coke oven with a charge of a length greater than that of the oven chamber, the combination of a charging peel adapted to be pushed forward into and withdrawn from the chamtherewith, of side plates attached to the porting the charge protruding from the oven chamber, an endplate carried by the framework and adapted to slide between the slide plate and means adapted to maintain the end plate against the charge as the peel and the framework are withdrawn from the chamber.

2. In a machine for charging a horizontal coke oven with a charge of a length greater than that of the oven chamber, the combina tion of a charging peel adapted to be pushed forward into and withdrawn from the chamber and a framework associated therewith, of side plates attached to the peel for supporting the charge protruding from the oven chamber, a guide plate carried work, tubes each supported by and having one end passing through the guide plates, an end plate fixed to the other ends of the tubes, and a resilient medium interposed between the guide plate and the end plate as and for the purpose described.

In a machine for charging a horizontal coke oven with a charge of a length greater peel for sup:
